IN-SITU STRESS MEASUREMENT BY DIFFERENTIAL STRAIN ANALYSIS METHOD IN THE WELL TUN-1
BAI Jin-peng, PENG Hua, ZHENG Zhe-xia, LIU Chong, MA Xiu-min, JIANG Jing-jie, LI Zhen
2013, 19(2): 117-124.
Abstract (403) HTML (284) PDF (2831KB)(50)
Abstract:
The principle method of the Differential Strain Analysis technique is briefly recommended. We tested the rock samples taken from the Well Tun-1 which was located in Luoyang-Yichuan basin in Henan Province. The results shows that the maximum horizontal principal stress is NW orientation (141°-157°) i...
NUMERICAL SIMULATION OF STRUCTURAL STRESS FIELD IN FUNING SEDIMENTARY PERIOD AND PREDICTION OF THE DEVELOPMENT LAW OF LOWER-ORDER FAULTS IN CHAJIAN SLOPE ZONE

Abstract (245) HTML (146) PDF (5619KB)(13)
Abstract:
Chajian slope zone is located in the south of the western slope, Jinhu sag. It has mainly experienced the Wubao and Sanduo tectonic movements during the sedimentation in Tertiary, which formed the complicated fault system and made it into a complex fault-block reservoir. There are many lower-order f...
A PRACTICAL ANSYS 3-D NUMERICAL SIMULATION METHOD FOR IN-SITU STRESS FIELD

2013, 19(2): 133-142.
Abstract (388) HTML (550) PDF (6853KB)(59)
Abstract:
In-situ stress field, which is consist of self-weight stress field and tectonic stress field, is one of the most important factors in the deep underground engineering analysis. There are some defects in present commonly used three dimensional stress field simulation method, then it is not very well ...
CALCULATING MODEL OF EQUIVALENT ROCK MECHANICAL PARAMETERS OF SAND-MUD INTERBED AND ITS APPLICATION
WANG Ke, DAI Jun-sheng, FENG Zhen-dong, XIE Yan-xue, FAN Yang, WANG Yuan, ZHAO Li-bin
2013, 19(2): 143-151.
Abstract (261) HTML (151) PDF (5942KB)(12)
Abstract:
On the basis of the deformation analysis of rocks and on the sense of energy, the general calculating formula of the equivalent rock mechanical parameters is deducted using strain energy theory and energy conservation law, and the logging data calculating model is established. The equivalent rock me...
STUDY ON PRESERVED-ORE FACTOR IN XIAZHUANG URANIUM ORE FIELD
ZHANG Wan-liang
2013, 19(2): 152-161, 187.
Abstract (320) HTML (132) PDF (9313KB)(8)
Abstract:
Xiazhuang ore field is the first granite-type uranium ore field found in China, where the deposits and occurrences located in the eastern part of Guidong grante, controlled by structure and lithology. About uranium mineralization type, there are silicified zone type (group vein), intersection type, ...
GEOCHRONOLOGY AND GEOCHEMISTRY OF THE HEINAOBAO PLUTON IN SIZIWANGQI, INNER MONGOLIA AND ITS TECTONIC EVOLUTION
XIONG Guang-qiang, ZHAO Hong-tao, LIU Min, ZHANG Da, WANG Hao-ran, WANG Zhong
2013, 19(2): 162-177.
Abstract (249) HTML (86) PDF (10253KB)(9)
Abstract:
Heinaobao granitoid in the Siziwangqi area of Inner Mongolia tectonically belongs to Early Paleozoic hyperplasia plate in the northern margin of the North China plate. The granitiod is predominantly of composed of granodiorite and granote porphyry. The La-ICP-MS U-Pb zircon dating method and petroch...

2013, 19(2): 178-187.
Abstract (288) HTML (127) PDF (10951KB)(26)
Abstract:
Based on detailed filed survey and deformation monitoring data for many years, deformation characteristics and formation mechanism of Xieliupo landslide in Zhouqu has been discussed. The result reveal that the landslide which lies in Pingding-Huama Fault Zone belong to a typical giant fault zone lan...
STABILITY RESEARCH OF TANGJIASHAN LANDSLIDE IN WENCHUAN EARTHQUAKE
YUE Gao-wei, LI Wen-zhe, WANG Hui, ZHAO Fa-suo
2013, 19(2): 188-197.
Abstract (224) HTML (117) PDF (7567KB)(19)
Abstract:
The numerical model of Tangjiashan landslide is established to analyze its slope stability with Mohr-Coulomb theory and the strength reduction method. Firstly, the slope stability is simulated numerically under the natural state (only with the gravity action), and the calculated safety factor is 1.4...
